Product details
In the EVX series, the CSB EVX12120 is a top-terminal 12V valve-regulated sealed lead-acid battery. It is manufactured using AGM (Absorbent Glass Mat) technology, with gas recombination efficiency up to 99%, combined with pure lead construction and a proprietary formula. The role of this series is as a durable deep-cycle VRLA pure lead battery series for electric mobility and cyclic energy storage applications, so applications requiring repeated charge and discharge fit it well.
First, mechanical and temperature conditions: length 151.0±2.0mm, width 98.0±1.0mm, height 100.3±1.5mm, weight approximately 3.83kg; ABS forms the housing, flame retardant rating is UL 94-HB, terminals are F2 Faston Tab 250. This battery operates maintenance-free, with 25°C marked as the normal operating temperature; the discharge range covers -15°C to 50°C, and the charge and storage range covers -15°C to 40°C.
Capacity and charging data are as follows: at 25°C and 1.75VPC, the nominal capacity at 20-hour rate is 12Ah; 8-hour rate capacity is 10.64Ah; at 8-hour rate and 1.80VPC, capacity is 10.56Ah. The charging side can withstand a maximum current of 3.60A, equalization charge voltage at 25°C is 14.4 to 15.0Vdc; internal resistance is 15.4mΩ, short-circuit current is 464A. When configuring charging equipment and matching systems, these values can serve as a reference.
In terms of cycle performance, 400 cycles can be achieved at 25°C and 100%DOD, and 1800 cycles at 30%DOD. For self-discharge, stored at 25°C for 90 days, capacity loss is less than 10%; maximum storage is 6 months, and a full charge is required before use. If storage temperature exceeds 25°C, recharge should be performed earlier. Manufacturing complies with IEC 60254-1:2005, IEC 60254-2:2008, and is UL1989 recognized (MH14533).
Overall, the EVX12120 integrates 12V voltage, 12Ah capacity, and deep-cycle characteristics, suitable for electric mobility and also for energy applications requiring cyclic charge and discharge. Valve-regulated sealed design combined with AGM construction enables maintenance-free use; pure lead construction and proprietary elements are used to meet durability requirements under cyclic conditions.
